ENGINEER: Arnold \ AG 

PV (kg/yr): Import Only 

SUBMITTER: Nanocyl Corporation 

USE: Plastics additive to improve electrical, thermal, and/or 

mechanical properties; additive to coatings. 

OTHER USES: 

 

 

 

 

 

MSDS: Yes Label: No 

Gen Eqpt: protecting gloves (e.g. nitrile rubber, thickness 

greater than 0.35 mm) / chemical goggles or safety glasses 

Respirator: suitable respiratory equipment with High Efficiency 

Dust Cartridge (at least a P2 filter) when directly exposed or 

handling the powder 

Health Effects: contact with eyes may cause irritation due to 

abrasive action of the dust; not expected to cause prolonged or 

significant eye irritation / skin contact: no known hazards, but 

may be mildly irritating to the skin; it is not expected to be 

absorbed through the intact skin / inhalation of the dust from 

this material may cause respiratory irritation / ingestion: no 

known hazards; not expected to be harmful if swallowed / acute 

and chronic health effects: high concentration of dusts may be 

irritating to eyes, skin, mucous membranes and respiratory tract; 

 no applicable chronic information at this moment, but none of 

the components is known to be a carcinogen or a suspected 

carcinogen 

TLV/PEL: 

Carbon nanotubes 2.5 ug/m^3 LOAEC (Low Observed Adverse Effect 

Concentration) Nanocyl recommends a LOAEC of 0.1 mg/m^3 and 

applies a safety factor of 40 to achieve an air threshold of 2.5 

ug/m^3. 

CRSS : 

Chemical Name: Multi-walled carbon nanotubes 

S-H20: 0.000001 g/L @ 

VP: 1.0E-6 torr @ 
MW: %<500 %<1000 

Physical State and Misc CRSS Info: 

Neat: Solid Mfg: NK: Import Proc/Form: NK End Use: Solid: LVE 

material entrained within polymer. The molecular weight is 

variable and depends on the size of the nanotube. It is 

expected to be much greater than 100,000 g/mole. The submitter 

claims that there are two kinds of nanotubes, short tangled 

nanotubes and long rigid nanotubes. This LVE is for the short 

tangled kind of carbon nanotubes. Submitted Data: Burns before 

melting; Insoluble in water; Average Diameter = 9.5 nm; Average 

Length = 1.5 μm; Surface Area = 250-300 m^2/g; Agglomerate 

Particle Size: 4.7% < 0.1mm, 58.5% 0.1-0.5 mm, 33.9% 0.5-1 mm, 2. 

9% 1-2 mm, 0% > 2mm by sieves, 10-2000 μm by light scattering at 

1 bar, 10-600 μm by light scattering at 4 bar; Stable up to 480 

°C in an oxidative atmosphere; Explodability: Kst = 42 bar*m/sec 

(VDI). Estimated Data: BP > 400 °C (High MW); VP < 0.000001 

torr (High MW); WS < 0.000001 g/L (High MW).

AG called Michelle Walker and received the following answers to 

the questions provided in the 3/11/09 contact report.

Ms. Walker will follow- up with 

Nanocyl for a further explanation on this. She will see if 

estimates are known for how many campaigns/year and/or days/year 

a customer would use the CNTs.
